Re: Building a dfs CD
i am glad you are working on this, i would like to make
one myself (not right away, but in the near future).
is it possible if you do it again (i assume you will after
etch is closer to finalized), can you run these commands
in an emacs shell and save the transcript to make available.
you could even if creative still work your comments in.
i am still uncertain of the ways here so apologies if we
are not supposed to ask people to do things, "you" refers
to anyone who would like to volunteer (myself included perhaps,
i am not sure i could do it yet but i might try )

I finally got my dfs cd going. The package, I believe, is geared towards
the i386 machines, also there are a couple of modifications that I
wanted. My final cd came in under 600M, about 585M. It did finally work
via the ofboot.b OF file. The following instructions may not be complete
since I may have forgotten to write a few items down. However, I don't
think I missed much. I also apologize if they are a bit cryptic in places.
- create dfs directory and iso "attempt" via the dfsbuild process
% dfsbuild -a powerpc -c /etc/dfsbuild/dfs.cfg -w dfsbuild
o need to not include pkgs: acpidump pnpbios-tools mdadm
- uncompress compressed directories if necessary
- remove any cached debs from the dfsbuild directories
- need to fix yaboot.conf wrt the root system references
- modify the initrd ram fs to include necessary drivers, such as for the
cd drive:
o Examine it by mounting it.
o Change it by copying it over to another directory, modify,
and recreate the ram w/ mkcramfs
o Increase the kernel ram size
(yaboot.conf) appropriately
o Copy marker over to new initrd
o Some changes: copied modprobe & made a link for ld.so.1,
added drivers
o will need to do a depmod
- separate out the boot directory from the others since it will not be
zftree compressed.
o create an hfs dir with the boot dir in it
o create an apple dir with the other (uncompressed) dirs in it
- will make a multi-session disk with boot on an 'hfs' session and the
rest on a 'apple' session.
- can reach the yaboot files on the CD from the OF prompt with: boot
cd:,\boot\yaboot
- to add packages to the dfs base directory do a chroot to an
uncompressed dfs directory, e.g.
% chroot apple-dir apt-get install somepkg
o Will need to change tmp and var/sub symlinks to point to
actual directories
o nb: for the following installs I had a local reprepro powerpc
mirror that I used.
-
install the xdm, xserver, xfonts, & wm (e.g. blackbox) pkgs in order
to have a gui
o May need to make X link in etc/X11 to usr/bin/X (server)
- install mrxvt and menu
- install any other pkgs one might like
- create hosts file in etc
- useful to make var/log writeable by moving it to opt/dfsruntime/runtimerd
o In general this is where anything that is needed to be
modifiable needs to be
- add a name server to resolv.conf (tho not abs. nec.)
- set password for root and export DISPLAY
- the CD can be burned by the following procedure:
# Make an hfs bootable session with the boot directory, e.g. a target
directory with boot
# Use this cmd to make the 1st (session) iso for a cd (if after dfsbuild
not doing it correctly)
mkisofs -o hfs_image.iso -v -v -r -part -hfs -no-desktop -map ./hfs.map
./hfs_target >> mkisofs.out 2>&1 &
# burn it with:
cdrecord -v -multi -dev=1,0,0
hfs_image.iso
# Retrive nec. info for 2nd (session) iso with:
cdrecord -msinfo -dev=1,0,0
0,17283 # for example
# in order to save space, the uncompressed directory tree must be
compressed via:
mkzftree -C apple_target-old apple_target_uc apple_target &
# And make it with (where the cd writer drive (e.g. /dev/scd0) can be
subbed for the hfs iso)
# the iso of the main directory is created by:
mkisofs -o apple_image.iso -v -v -r -z -part -apple -C 0,17283 -M
hfs_image.iso -no-desktop -map ./hfs.map ./apple_target >> mkisofs.out
2>&1 &
# and burn it with:
cdrecord -v -dev=1,0,0 -multi apple_image.iso
